Here's something that looks really interesting for all the P2P lovers;

RetroShare is a cross-platform private p2p sharing program. It lets you share securely with your friends, using a web-of-trust to authenticate peers and OpenSSL to encrypt all communication. RetroShare provides filesharing, chat, messages and channels

Hello, don't share anything illegal on that network unless you know your "friends" IRL.Somebody was judged guilty of sharing copyrighted files in Germany some weeks ago.One of his "friends" picked on a Retroshare forum was in fact a copyright troll !!
